基于知识本体的过程安全分析信息标准化

过程危险分析的主要目标是识别危险剧情。危险剧情能够表达团队“头脑风暴”安全评价过程也能表达评价结论。危险剧情的知识本体是标准化过程安全分析信息的准确描述。知识本体是概念表达的明确规范。依据设计知识本体所遵循的规则提出了一种过程安全分析信息标准化方法，称为剧情对象模型（scenario object model，SOM）。SOM能够表达安全分析信息的内容和结构，能够实施计算机自动推理和半定量计算。应用知识本体SOM有效实现了计算机辅助自动安全评价和安全信息的传递、复查和共享。

Standardized information for process hazard analysis based on ontology

The principal objective of process hazard analysis is to identify hazard scenarios.Both the course of team brainstorming hazard evaluation and its result information can be expressed as hazard scenarios.Ontology of hazard scenarios is accurate expression of standardized process hazard analysis information.An ontology is an explicit specification of a conceptualization.According to design criteria for ontologies,a standardized process hazard analysis information called scenario object model(SOM)was proposed.SOM was used to represent contents and structures of hazard evaluation information.Computer automatic reasoning and semi-quantitative algorithms could be implemented on SOM.Computer-aided automatic hazard evaluation and transfer,auditing and sharing of safety information were realized effectively by using ontology SOM.
